Answer:

Step-by-step explanation:

Create a proportion

$\frac{x}{12} = \frac{63}{84}$

84 divide by what gives you 12? 7

So divide 63 by 7, and you get 9.

This doesn't work with all of these problems so you can always cross multiply then divide.

12(63) = 756

84(x) = 84x

84x = 756

84x/84 = 756/84

x = 9

Evaluate the function at the given value and simplify.

Licemer1 [7]

Answer:

The correct option is b.

Step-by-step explanation:

The given function is

$f(x)=-5x+1$

We need to find the value of f(-2). It means we have to find the value of given function at x=-2.

Substitute x=-2 in the given function to find the value of f(-2).

$f(-2)=-5(-2)+1$

On simplification we get

$f(-2)=10+1$

$f(-2)=11$

The value of f(-2) is 11. Therefore the correct option is b.
